One Model vs Workday

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

Starting price

One Model

Sales-quoted

Enterprise people-analytics platform that unifies HR data and adds AI Q&A plus an MCP server. Pricing is quote-based.

Where One Model fits

  • Enterprise people-analytics teams on Workday or SAP
  • CHROs who need board-ready workforce stories
  • Teams that want AI chat on governed HR data
  • Companies replacing spreadsheet HR metrics

Workday

Sales-quoted

Enterprise HCM of record where recruiting is one module. Quote only, with long implementations and a tenant-scoped MCP rather than a public one.

Where Workday fits

  • Global enterprises already on Workday
  • HR IT teams standardising the HCM
  • Talent teams that must live in the system of record
  • Selections that name Workday Recruiting

Where they pull apart

One Model

Stands out: MCP lets Claude, Copilot, and ChatGPT query governed workforce data instead of a generic model.

Watch out: Editions are named but unpublished. One AI predictive modeling is Enterprise-only. MCP is an add-on on lower editions.

Not the right fit for

  • Small HR teams that want self-serve pricing
  • Buyers who only need a simple pulse survey

Workday

Stands out: It is the system of record for very large companies; recruiting rides along with it.

Watch out: Recruiter sentiment is among the most negative of any platform here, and implementations run long.

Not the right fit for

  • Small businesses
  • Agencies
  • Teams that want a public MCP endpoint
